INTRODUCTION Thank you for purchasing this model of the standby gen- erator set product line by Generac Power Systems. Every effort was expended to make sure that the infor- mation and instructions in this manual were both accu- rate and current at the time the manual was written.
Important Safety Instructions Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators SAVE THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted in potential hazard areas. Safety should be stressed to all operators, potential operators, and service and repair technicians for this equipment.
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators • Inspect the generator regularly, and promptly repair or replace all worn, damaged or defective parts using only factory-approved parts. • Before performing any maintenance on the generator, disconnect its battery cables to prevent accidental start-up.
Section 1 - General Information Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators GENERATOR This equipment is an water-cooled, engine-driven gen- erator set. The generator is designed to supply electrical power that operates critical electrical loads during util- ity power failure.
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators Figure 3 represents a single-phase, 3-wire generator AC connection system. The stator assembly in this system consists of a pair of stationary windings, with two leads brought out of each winding. Each single winding can supply 120 volts AC, 60 Hertz.
Section 1 — General Information Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators LOW COOLANT LEVEL SWITCH: Should engine coolant level drop below the level of the high coolant temperature switch, it is possible for the engine to overheat without automatic shutdown.
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators INSPECTION: After unpacking, carefully inspect the generator for any damage that may have occurred during shipment. If loss or damage is noted at the time of delivery, have the person(s) making delivery note all damage on the freight bill or affix his signature under the consignor’s memo of loss or damage.
Section 1 — General Information Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators BEFORE INSTALLATION Before installing this equipment, check the ratings of both the generator and the transfer switch. Read “Emergency Isolation Method” and “Total Circuit Isolation Method”...
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators Connecting this generator to an electrical system normally supplied by an electric utility shall be by means of a transfer switch (such as the Generac “GTS” type transfer switch), so as to isolate the electric system from the utility distribution system when the generator is operating.
Section 2 — Installation Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators EMERGENCY CIRCUIT ISOLATION METHOD This prevents overloading the generator by keeping elec- trical loads below the wattage/amperage capacity of the generator. If the generator is powering only critical loads, within the wattage/amperage capacity, during util- ity power outages, you might consider using the emer- gency circuit isolation method.
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators an explosion. Such an explosion can shatter the bat- tery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery.
Section 3 — Operation Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators Fuel System Make sure the fuel supply system to the generator (a) delivers the correct fuel at the correct pressure and (b) is properly purged and leak tested according code.
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators CONTROL CONSOLE COMPONENTS The components of a water-cooled generator control console (Figure 8) are as follows: Figure 8 - Water-Cooled Generator Panel AC VOLTMETER: The voltmeter displays generator AC output voltage dur- ing operation.
Section 3 — Operation Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators RETRANSFER AND SHUTDOWN When utility power source voltage has been restored, electrical loads may be transferred back to that source and the generator can be shut down as follows: •...
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators MAINTENANCE PERFORMED BY AUTHORIZED SERVICE FACILITIES A. EVERY THREE MONTHS 1.Check battery state of charge and condition. 2.Inspect and test fuel system. 3.Check transfer switch. 4.Inspect exhaust system. 5.Check engine ignition system.
Guardian Liquid-cooled 10 kW, 15 kW, 20 kW and 25 kW Generators CAUTION: After refilling the crankcase with oil, always check oil level on dipstick. NEVER OPERATE ENGINE WITH OIL BELOW THE DIP- STICK “ADD” MARK. 7.Start engine and check for oil leaks. COOLANT CHANGE Every year, have Authorized Service Facility drain, flush and refill the cooling system.
